Sister said for me to send her songs I want her and the band to cover when they play tomorrow 😬

I can only choose three songs to include in their set and they all have to be relatively well-known; ones her and the band are already familiar with or can learn to perform within a day. Damn, this is always so hard to do because I have so many I'd love to hear my sister sing, yet have such a limited selection in both the amount of songs I can pick and her and the band will know how to perform. 😩
